After the overhaul is finished, the cabinet door 17 is installed, the second switch valve 13, the third switch valve 15, the fifth switch valve 10 and the seventh switch valve 25 are opened, the rest valves are closed, and the insulating cooling liquid enters the circulating pump 2 from the liquid storage tank 6 and enters the bottom of the cabinet body 1 after passing through the filter 16 and the radiator 3. When the insulating cooling liquid in the cabinet body 1 flows back to the height position of the liquid return port 23, the first switch valve 14 is opened, the circulating pump 2 is started, and the circulating pump 2 simultaneously extracts the insulating cooling liquid from the upper parts of the liquid storage tank 6 and the power distribution cabinet. After the insulating cooling liquid can form a circulation from the tank, the circulating pump 2, the filter 16 and the radiator 3, the fifth switch valve 10 and the seventh switch valve 25 are closed, so far, the submerged electrical cabinet is restored to the running state, at this time, the first switch valve 14, the second switch valve 13 and the third switch valve 15 are opened, the rest switch valves are closed, and the circulating pump 2 and the radiator 3 are opened. In one possible embodiment, the control mode and the control flow of each device (the circulation pump 2, the radiator 3) and the switch valve (the first to seventh switch valves) in different states of the submerged electrical cabinet can be recorded in the control device 21, and by sending a control instruction (for example, an overhaul instruction, an operation recovery instruction, and an operation stop instruction) to the control device 21, the control device 21 controls the operation of each device and the switch valve according to the control instruction, so that the work efficiency is improved.
As described above, by placing the insulating cooling liquid in the sealed cabinet 1, pumping out the insulating cooling liquid in the cabinet 1 through the circulating pump 2 via the circulating liquid return pipe 4, and circulating and flowing back into the cabinet 1 through the circulating liquid inlet pipe 5, in the process of continuous circulating and flowing back of the insulating cooling liquid, the insulating cooling liquid contacts with the electrical elements in the cabinet 1 and takes away heat of the electrical elements, so as to cool the electrical elements in the cabinet 1, and after being pumped out from the cabinet 1, the insulating cooling liquid is cooled by the radiator 3 and then flows back into the cabinet 1, so as to improve cooling efficiency, ensure that the electrical cabinet obtains effective heat dissipation, and ensure working stability and safety. The immersed liquid-cooled electrical cabinet is high in heat transfer efficiency, and can quickly take away heat emitted by an electrical element, so that the electrical cabinet can operate in a proper temperature range, the faults of the electrical element caused by dust, vibration, humidity, static electricity and the like in the traditional air-cooled electrical cabinet are effectively reduced, the service life of the electrical element is prolonged, and noise generated in the heat dissipation process is effectively reduced. Meanwhile, the insulating cooling liquid is used for cooling the electric elements, so that the generation of electric arcs in the electric cabinet is effectively reduced, and the safety and the stability of the electric cabinet are improved.
The foregoing is considered as illustrative of the preferred embodiments of the invention and the technical principles employed. The present application is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present application has been described in more detail with reference to the above embodiments, the present application is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present application, and the scope of the present application is determined by the scope of the claims.
